Topic 1.3 - Mass and Weight Flashcards
1
Q
Define mass.
A
The amount of matter contained in an object, and a measure of its resistance to acceleration.
2
Q
Define weight
A
The force acting on an object due the effects of its mass and gravity.
3
Q
Give the equation for weight, including all SI units.
A
Weight (N) = mass (kg) x gravitational field strength (kg/N)
4
Q
What does g represent?
A
The gravitational field strength.
5
Q
How can weight be measured?
A
- A force meter (spring balance)
- A weighing scale, which measures weight and converts it into mass (by dividing by g)
